A new study sheds light on how the body fights back against HIV by mutating the viral DNA.

Scientists have engineered a mouse model to study a rare and often-fatal form of liver cancer. They’ve used it to clarify what drives these tumors at the molecular level, and discover new drug concepts.

Scientists have discovered a peculiarity in the genetic code of HIV that might explain how this and other viruses evolved ways to dodge our immune system. The findings could make it possible to develop safer vaccines.

Scientists have identified a protein that many viruses require to spread within a host—a discovery that could lead to fighting diseases as varied as parainfluenza, West Nile, and Zika with a single drug. This finding could also lead to the development of treatments for emerging viruses.

One of the most prestigious funding programs in the world, the MacArthur fellows program awards grants to exceptionally creative individuals as an investment in their potential.

Scientists have found unexpected differences in how male and female mice respond to stress. Their findings are raising big questions about sex discrepancies in the brain and their impact on neuropsychiatric disease.

To keep up with evasive flu viruses, new vaccines must be developed each year. Scientists are devising a strategy to better prevent the disease without annual shots.

Scientists found that a system called CRISPR-Cas10 can target rapidly mutating viruses.

Scientists developed a method to genetically engineer gut bacteria to produce molecules that have the potential to treat certain disorders by altering human metabolism.

The prestigious award honors Marraffini and four other scientists for development of the revolutionary genome-editing system known as CRISPR-Cas9.
